Define macros MBEDTLS_CHECK_RETURN_CRITICAL, MBEDTLS_CHECK_RETURN_TYPICAL
and MBEDTLS_CHECK_RETURN_OPTIONAL so that we can indicate on a
function-by-function basis whether checking the function's return value is
almost always necessary (CRITICAL), typically necessary in portable
applications but unnecessary in some reasonable cases (TYPICAL), or
typically unnecessary (OPTIONAL).
Update the documentation of MBEDTLS_CHECK_RETURN accordingly. This is split
between the user documentation (Doxygen, in config.h) and the internal
documentation (non-Doxygen, in platform_util.h, of minor importance since
the macro isn't meant to be used directly).

The API reached 1.0.0 some time ago, and we've caught up with the
incompatible changes already.

The numerical identifier of the CID extension hasn't been settled yet
and different implementations use values from different drafts. Allow
configuring the value at compile time.

Any config with a version older than 3.0.0 or newer than
MBETLS_VERSION_NUMBER will be rejected.
This does mean that the current development version doesn'T accept *any*
value of MBETLS_CONFIG_VERSION, but this will be fixed when we bump the
version during our normal release process.
